Trader sentiment for Karachi's August 26 overnight low reflects substantial forecast uncertainty, with closely matched probabilities around 26–27°C driven by variable monsoon influences two days out. Pakistan Meteorological Department guidance and global models highlight how incoming Arabian Sea currents could increase cloud cover and scattered showers, limiting nocturnal radiative cooling and elevating minimums above the historical August average of roughly 27°C. Conversely, stronger sea breezes or clearer intervals might allow greater cooling toward the mid-20s. Short-range model spreads remain wide due to timing of any thundershowers and humidity levels, with fresh PMD updates and satellite observations expected to narrow the range before resolution.
